Note: You have to be the owner of your account in order to access the "Billing & Invoices" section. You can refer this FAQ to find the owner of your account.
Invoices are sent with every successful payment via email to the registered email address. They can also be downloaded from Billing & Invoices, once you are signed in. You can also have invoices billed to multiple recipients by adding addresses (separated by a comma (,) without space) under 'Update your Bill-to address'. Please contact us for bank transfers and POs.
